Helideck Design Considerations - Environmental Effects

The report contains guidance on good offshore helideck design practise in terms of environmental issues. This material was generated in support of Offshore Helideck Design Guidelines document published by the Health & Safety Commission on behalf of the Offshore Industry Advisory Committee Helicopter Liaison Group, and forms a section within that document. This material was originally published in CAA Paper 2004/02, and has been updated to take account of progress in several research areas. In particular, a turbulence criterion has been introduced and the original vertical flow criterion removed (see CAA Papers 2004/03 and 2008/02).
